TYPEWRI'IING MACHINE. 1

Application led November 9, 1922. Serial No. 599,863.v I

To all whom t may concern.'

Be it known that I, EDWARD B. Hass, a citizen of the United States, residin in Manhattan Beach, in the county of ings and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specication.

This invention relates to the paper tables of typewriting machines which are provided with adjustable paper gages and margin scales for positioning the edges of the paper relatively to the printing point and for guiding the paper over the tablel in such manner as to obtain the desired margin. Devices for this purpose are shown in my Patents 1,168,207 of January 11, 1916, and 1,417,903 of May 30, 1922, and in the pending application of Walter D. Camp, No. 560,707, led May 13, 1922. In said application the table shown is provided with a margin scale plate secured in a recess at the left-'hand side of the table and the gage or paper guide is so mounted as to move across the scale.` No gage or paper guide is provided at the Oppositel or right hand end of the table andtherefore no provision is made for regulating the margin there.

It is often desirable not -only to regulate the margin at the left hand end of the table, but also at the opposite end thereof. This is particularly the case when using cards and accordin to my invention, the table is provided wit a scale which extends from one end of the table to the other, and the table is also provided with paper gages for regulating both margins. Inasmuch as it is not generally necessary to regulate the right hand margin, provision is made for moving the right hand gage from its operative position on the table to a position above the upper edge of the table or to a position behind the table when desired.

The scale, which as before stated, ex tends from one end of the table to the other, is calibrated and numbered in opposite directions from a zero point which latter is located nearer to one end of the table than to the other. The devices pivotally connecting one of the paper gages to the carriage are of novel construction and will be hereinafter more fully described.

In the accompanying drawings,

Figure 1 is a vertical section through parts slot t2 in the table and of a Royal standard typewriting machine, with my improvements applied.'

Figure 2 shows a rear elevation of some of the parts illustrated in Figure 1, the manner in which the view is taken being indicated bfy the arrows in Figure 1. p p

Figure 4 is a detail sectional view of some of the devicesemployed for pivotally connecting one of the paper gages with its sup'- port.

Figure 5 isa'front elevation of the paper table equipped with the paper gages and the margin scale made in accordance with my invention, both gages being in operative' position.

Figure 6 is a similar viewl with one of the gages shown by dotted line moved to in-` operative position. A

.Figure 7 is a view ofthe marginal' scale and stop,

' Parts of the side plates of a typewriter y carriage frame'are indicated at A. C rep' I resents a margin rail, and E `a portion Of-ia paper pan which'latter is supported b a frame piece F carrying a strip or pad of y felt or similar soft material which serves as a cushion for the table when swung from its raised to its working position.

The paper table Tis carried by two sup-l other. `This scale may be applied to the table in any suitable way, but preferably the graduations and numbers are formed on or applied to a metal strip arranged in a recess or depression in the table. The opposite ends of the scale plate or metal stripl extend through openings tin, the table as shown and as more fully described inthe application of Walter D. Campyabove re-v ferred to. In view-of the ,length-'Of the metal strip and in order to prevent buckling thereof the middlev portion of the strip is provided with devices for adjustably securing it to the table. These devices may consist of a short bolt t extending through a provided with a tightening nut t3.

The scale K bears numbers running in opposite directions ,to Ithe right and Vto the left from ya vZero point, which is located nearer' to one end of the table than the otherpreferably near the left hand end as shown.

The paper gage M- at the left hand of the table is similar-'in construction to that shown in the application of Walter D. Camp above mentioned and operates in a similar way. This gage is supported on a tie rod N extending from one side of arm hinged to thecarriage frame to the other. lt is adjustable transversely across the table to the de sired. extent, but yno provision is made for giving it other adjustments, as other adjustmen-ts are not as a rule required at the left .hand end of ,the table. The right end gage O, however ,isv so constructed and mounted that it may be adjusted lengthwise of the tabley to the desired extent and may also be moved from operative position to inoperavk.tive position above the table top, or to a position in rear yof the table. For this purpose the gage is pivotally connected at g with the arm g of a bracket Q which is mountedy to slide on the tie rod N. As

clearly shown in Figure l, the lower end of y rod', and having an upper portion which is bolted to the bracket Q., at R. The clamp has a lower portion or arm r2, which serves to retard the rearward movement of the gage when the latter is swung rearwardly to the ndotted line position show-n.

The devices shown for pivotally connecting the gage O with ythe bracketV Q are of novel construction permitting the gage to be readily turned from `operative' to inoperative position, and yieldin'gly held in either position. The gage 0 is formed at its upper end with Va lu or arm 0 which carries a rearwardly exten ing pin or arm s threaded at the outer end to receive the hollow nut S enclosing a spiral spring U which surrounds the pin. Thearm g of the bracket is formed with a central opening through which the pin s extends and in which-.is supported a block V in which the pin turns. rhe rear .end of the block V is Jformed with a series of recesses o adapted to receive 4antii'riction balls W which are held in place by a disc X having openings :e into which the balls W project. Thespring U yieldingly holds the disc iny engagement with the balls in such manner that they can not be -dislodged from the recesses e in the block V.

The disc X can move toa limited extent endwise of 'the s but it is prevented from turning thereon by a lug or key which projects from the disc and enters a longitudinal groove s. in the pin. By this construction the gage O is so supported as to be properly held in its adjusted position and may be readily turned from operative posi-y tion on the table to a position at the upper end thereof. In operation the disc X recedes to a small extent when the gage carrying the pin and disc is turned to anew position and untilthe lballs again enter the holes in the disc` ln this way the gage G may be exactly yadjusted and properly held in the desired position.

The gage may be merely moved to a position shown by the-dotted linefin Figure 6 at the upper edge orl the table or, if desired, it may be moved to d position behind the table as indicated by dotted yline in Figure l, .the rearward movement or the.

gage being limited by the arm r2 `which abuts against the rear side of the table..y

The arm N shown in Figure l is a part of the device shown in the application of Walter D. Camp for mounting the gage M.

While I have shown my invention embodied in a typewriting machine or ythe Royal standard type, it will be understood that it may be embodied invmachines of various kinds. As explained in the applicaf tion of l/Valter D. Camp above mentioned, -i

the paper gages are associated in such mannerwith the margin scale on the table and the margin scales lon the margin kstop.

bar that it is impossible 4to adjustthe .gage definitely a given number of scale spaces corresponding withl the letter spaces on the machine. It isfto be understood `that the scale spacing of the scale plate K corresponds with Lthe letterv spaces on all other scales in the machine.- The manner in which the gage is used may be understood from av single illustration. If the gage M is located: at zero, and the marginv stop C on themachine is set at 10, itwould-indicate that there would be l0 spaces from the edge of the sheet to be written upon to apoint where printing would begin, and if it be desired toadd tive more letter spaces or to diminish the margin to that extent, it wouldbe unnecessary for the operato-r to adjust the marginand maintained at allv times in case it is.

desired to move the gage toa position to the right to use the paper narrower than ythe standard width, and where a set margin is still desired. In a similar way the gage `O atthe right hand end ofthe tablemayfbe`v adjusted over the scale to the right ofi the zero point. l

I claim as my invention:

l. A paper table having scale plate receiving openings near each end, and al1-intervening plate receiving. recess in combination with a scale plate seated in said recess, having its opposite ends extending through. the openings at the ends of the plate and provided with devices for securing its middle portion to the table.

2. A paper table having scale plate receiving openings near each end and an intervening recess in combination with an endwise adjustable scale plate seated in said recess, having its opposite ends extending through said openings, and provided with devices for adjustably connecting its middle portion to the table.

3. The combination with the paper table of a typewriting machine of a paper gage having a supporting bracket mounted in rear of the table and an arm extending through the bracket, a bearing block carried by the bracket through which the arm eX- tends, and devices carried by the arm for yieldingly resisting the turning movement of the arm. v

1l. The combination with the paper table of atypewriting machine of a paper gage having a supporting bracket mounted in rear of the table and an arm extending the disc in engagement of a typewriting machine oi' a paper gage having a rearwardly extending pin or arm, a bracket mounted to move lengthwise of the table which supports the gage, a bearing block suppor-ted by the bracket through which the arm of the gage extends and which is formed with recesses at its rear end, balls mounted in said recesses, a perforated disc engaging the balls: when mounted on the arm ot' the gage to turn therewith and to slide longitudinally thereon, a recessed nut carried by the gage arm and al spring housed in said nut whichpresses the`-disc into engagement with the balls.

In testimony whereof, I have hereunto subscribed my name.
